BLANK FOR LAClNG-STUDS.

SPECIFICATION forming part of Letters Patent No. 258,532, dated May 23, 1882.

Application filed April 1,1881. (N0 model.)

To all whom it may concern:

Be it known that I, Lonrs GonDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Blanks for Shoe-Fastenings or Lacing-Stnds, of which the following description, in connection with the accompanying drawings, is a specification.

This invention has for its object a novel construction or shape ofa blank from which to make a shoe -fastening or lacing-stud of that class having an eyelet-shank for attachment with the shoe.

Figure 1 represents in full and dotted lines a piece of sheet metal of a shape to form two blanks, capable of being formed into two fastenings, such as shown in Fig.2. Fig. 2 is a vertical section of a fastening after bending the larger portion of the sheet-metal blank to form the eyeletshank. Fig. 3 is a vertical section of a fastening made from one of my improved blanks, the same being shown bent into shape; and Fig. 4 is a top view of Fig. 3.

In the manufacture of a fastening I take a sheet-metal plate and cut it into blanks a, such as shown in full lines,Fig.1,that form of blank giving substantially the proper shape for the production, with the least waste of metal, of the complete fastening 1). Referring to the said sheet-metal blank, the portion 2 is that which forms the hook of the fastening, the said book being designated by the same figure in all the views. The remaining portion of the blank, placed on a bed or die under a punch, is acted upon and bent into cylindrical shape, the ends of the blank being abutted together, as in Fig. 4, to form the eyelet-shank b, leavbe laid upon the top of the shank part I), and I by means of another die (not shown, but of suitable shape) acting upon the under side of the part 2, the said part may be laid over upon the rounded end of the said die, bending and setting the part 2 into the shape shown in Fig. 3, curving or concaving it, as shown clearly in Fig. 4, to give to the hook part 2 greater strength and stiffness.

The one-piece sheetmetal eyelet may be cheaply and rapidly made, and be quickly set in a shoe by means of an eyelet-setting machine.

The pronged part 4 of the blank enters into and forms the flange 3 of the fastening when the ends as 00 of the blank, bent into cylindrical form, are brought together, as in Figs. 2 and 4.

I do not herein broadly claim a fastening herein shown as an improved article of manufacture, as that I reserve for another application.

I claim- The sheet-metal eyelet-blank (I, having the hook 2 and pronged part to form the upper flanged rim of the eyelet, substantially as described.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
